CarbonCharts: Export carbon styles

[silvalaura]

Currently our Carbon charts look great on Storybook, but don't have the correct styles in the docs site or when consuming it directly (ie CodeSandbox). This is because we are not exporting the carbon styles (@carbon/charts/styles.css) with our charts bundle. If we try to add that import when using our charts, then all our custom magma styles get overwritten.

Acceptance Criteria:

• The carbon styles are part of the charts package so a user doesn't need to add any additional dependencies when consuming charts.

Something happened to the titles and padding of the modal.

I didn't realize this would show up in the actual documentation, but we don't actually want to call this thing "CarbonChart." We should be transparent in the documentation that we use Carbon, but we want internal users to view this simply as "Charts."

I think it was intended for there to be a link in the opening paragraph of the docs, but it isn't rendering that way.

I have reviewed the updates and everything is looking good to me.
